Abstract

Methods systems computer readable media and apparatuses for determining locations of access points (AP) are presented. Techniques are described for determining relative and absolute locations of APs. In one embodiment a device may send and receive messages to one or more APs for from various locations for determining the distance between the device and the AP. The device may additionally keep track of its own displacement for the purposes of determining the location of the one or more APs. In one embodiment the device also determines the turnaround calibration factor (TCF) for the AP that compensates for the processing time at the AP may also be used for increasing the accuracy of the determination of the location of the AP.
